`HARRY WALTER, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR T() GEORGE W.TEUFEL, OF SAME PLACE.

DENTAL FORCEPS.

SPECIFICATION forming part of Letters Patent No. 511,067, dated December19, 1893.

Application tiled March 23. 1893- Serial No. 467i305. (No model.)

Tooll whom t may concern.'

Be it known that I, HARRY WALTER, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Improvement in Dental Forceps forVeterinary Purposes, which improvement is fully set forth in thefollowing specification and accompanying drawings.

My invention consists of dental forceps for veterinayy purposes, havinga fulcrum plate connected with the axis of the jaws, said plate beingformed of an arm which is secured at its inner end to the jaws of theforceps at the axis thereof, and a shoe connected with the outer end ofsaid arm, the inner end of the arm having a bearing against the portionof the jaws in front of said axis, as will be hereinafter fully setforth.

Figure l represents a perspective view of veterinary dental forcepsembodying my invention. Fig. 2 represents a plan View of a portionthereof. Fig. 3 represents a section of a portion on line an, fr, Fig.2.

Similar letters of lreference indicate corresponding parts in theseveral figures.

Referring to the drawings: A designates a pair of' dental forceps forveterinary purposes.

B designates the axis or axial piu of the jaws or beaks, and Cdesignates an arm which is connected with said axis and extends forwardbetween said jaws, and has fitted to its outer end, in an eye thereon,the screw stem D, to which is connected the shoe E, it being seen thatby screwing the stem D in proper direction, the shoe E may be set nearerto or `farther from the arm C, and thus adjusted according torequirements. Y

The portion C of the arm C between the screw F, and thejaws or beaks ofthe forceps bear against the side of the portion of the forceps about oraround the axis, so as to provide a firm bearing for the arm againstsaid portion, and thus increase the durability of the axial portion ofsaid arm.

The ends of the shoe are hanged so as to prevent the same from `lateraldisplacement from the tooth on which it is supported.

The operation is as follows: The shoe is placed upon the crown or faceof a proper tooth, while the jaws or beaks are presented to the tooth tobe extracted, said shoe thus' providing a fnlcrum bywhich the forcepsmay be operated in a convenient and power ful manner. It will befurthermore seen, that the arm or bar C passes freely between, the beaksor jaws without interfering with the operation of the latter. The aXisBof the jaws is hollow, and receives a screw F, by which the arm C isconnected with the forceps, it being evident thatvwhen said screw isremoved, the arm C and lparts carried by the same, are disconnected fromthe forceps, and

the latter may be used without the fulcrum` attachment, as they are leftintact and unaffected by such displacement. When the arm is properlylocated, the screw may be applied, thus connecting the former with theforceps, it being evident that the arxn may turn on the screw F as itsaxis, and the shoe E may also turn on said arm C, thus permitting theadjustment of the forceps to the tooth to be extracted, while the shoerests upon the face or crown of the proper tooth as a bearing.

It will be noticed that by 4having thearm C extended in front of thejaws, the said arm with the shoe thereinis not in the way of the handlein operating the device, and also that a bearing is obtained at adistance from the tooth operated on, giving thereby more freedom or easein handling the forceps.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is*- 1. A dental forceps consisting of pivotedjaws, a forwardly projecting arm the axial pin connecting said arm withsaid jaws, and a shoe having a stem which is fitted in an eye in theouter end of said arm, the inner end of said arm resting against part ofthe forceps in front of the axis thereof, substantially as described.

2. Forceps having an arm, and a fulcrurn shoe with a stem on its backsecured thereto, said arm projecting forwardly between the beaksthereof, and having its inner end resting against part of the forceps,substantially as described.

3. A dental forceps having a hollow axial pin, an arm adj ustablysecured to said pin, and a fnlcrum shoe secured to said arm, said partsbeing combined substantiallly as described.
